Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 244 Issued at 2200Z on 01 Sep 2019
IA. Analysis of Solar Active Regions and Activity from 31/2100Z to
01/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 1 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (02 Sep, 03 Sep, 04 Sep).
IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic
field has been at active to major storm levels for the past 24 hours.
Solar wind speed reached a peak of 835 km/s at 01/0106Z. Total IMF
reached 8 nT at 01/1508Z. The maximum southward component of Bz reached
-7 nT at 01/1332Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 53007 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on day one (02 Sep), quiet to
unsettled levels on day two (03 Sep) and quiet levels on day three (04
Sep).
